' rest of'the chairs.

The principal object of the invention is to provide a device of this nature for holding a towel used for covering a head-restwhich can easily be attached to a dental chair without any alteration of the chair. 7

Another object of the invention is to Pro vide a device of this kind having means for resiliently gripping a paper towel used for covering a head-rest which can be attached to any makeof dental chairs.

Other objects ofthe invention will appear as thedisclosure progresses. The drawings are intended to merelyindicate apossible embodiment of the invention. It is obvious that the actual needs 'ofmanufacture may necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment illustrated but rath- '7 er to define such limits in the appended claim. For a more general understanding of the invention attention is called to the drawings. In these drawings'like' reference characters denote like parts throughout the specification.

Figure 1 is a view of a dental chairshowing the device attached thereto.

Figure 2 isa top view of the devicedetached from the dental chair.

Figure 3 is an edge view thereof.

Figure 4 is a side view of a modified form of the invention. 7 r

Figure 5 is a top view thereof.

Figure 6 isa view of the towel.

Referring now to the drawings in detail,

numeral 1 .designates the dental chair and 2 the usual horizontal arm for supporting the head-rest 3. Fastened to the arm 2 is a clamp 4 for holding a paper towel 5 by the end 6 The body of the towel is adapted to cover the head-rest while the end 7 r is adapted to curl underneath as shown in Figure "1 soas nation of a split ring member, of a screw for n'ot'to interfere with the patientsback.

member 10 attached to the resilient arm 9 for gripping the end 6 of the towel around the arm 2. The split ring member is provided with two ears'll and 12 for engagement with a screw 13 for tensioning the clamp around The ear 11 is thicker than the ear 12 and is threaded to fit the thread of the screw while the ear 12 is provided with. a hole large enough to clear the screw. The resilient arm 9 is preferably a flat spring member and riveted to the ring 8 at the top by a pair of rivets 14. "The saddle member err- 10 is curved to matchthe contour of the arm 2 and attached thereto is a button 15 for manually lifting the saddle member when it is desired to remove or insert a towel. The

arm 9 is so tensioned that the saddle member 10 will always bear with a certain degree of pressure against the arm 2. It will thus be seen that'the towelcan easily be removed or replaced by, simply lifting the button 15.

In Figures .4 and 5 is shown a modified clampthesplit ring member 16 andthe sad- 'dle member 17 are all made of one-piece of material. The split ring member and the saddle member is the same as shown in F ig-. ure 1 but instead of a separate resilient arm, the arm18 of the modified form of the, invention is made integrally with the said ring'and saddle members. The arm 18 extends to the :left of the split ring in a horizontal plane formv of the invention. 7 In this form of and then makes a comparatively wide turn as at 19 and then slopes-downwardly beyond the ring member. In other respects the action of the device is the same asin the pre ferred form of the invention.

It will thus be seen that I have provided a simple and efficient device for clamping a towel to a head-rest of a dental chair. The clamp can be attached to practically any make of dental. chair without any alteration I of either the clamp or chair. I

Having described my invention, I cla1m In a clip of the class described, the combiinglaterally of-said split ring member and the other portion bent over the first mentioned portion and extending beyond the said split ring member, and a spoon-shaped saddle member at the end of the said second 5 mentioned portion of the resilient arm, sald saddle member comprising a substantially circular disk curved downwardly in one plane.

In testimony whereof I aflix my signature.
